MDD025C-N-100-N2K-040FB0
The MDD025C-N-100-N2K-040FB0 is a compact synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is supplied for use with digital drive controllers, where it converts regulated inverter current into rotary motion for lightweight axes and spindle functions in automated machines. By combining a permanent-magnet rotor with electronic commutation, the unit supports precise velocity and position control in coordinated motion systems. This layout suits compact automation equipment that requires repeatable movement without a large motor footprint.
The servo delivers a continuous standstill torque of 0.90 Nm, giving the drive enough holding force for small positioning tables without overheating. At a nominal speed of 10000 rpm, it can maintain rapid cycle rates in pick-and-place or tool-change assemblies. Mechanical alignment to adjoining frames is aided by a centering diameter of 40 mm, and all power and feedback plugs face Side B of the housing, which helps in tight cabinet layouts. The shaft uses standard balancing, and the motor is supplied without a blocking brake to reduce mass on high-speed shafts. A factory-installed integrated absolute encoder reports multi-turn position data, allowing position information to remain available immediately after power-up.
The motor uses a connector interface so that power, resolver leads, and thermal contacts can be disconnected without opening a terminal box. The secondary feedback channel is provided by resolver feedback, which offers noise-resistant signal transmission for servo loops that operate near switching power supplies. A plain shaft without a keyway reduces coupling complexity, while the standard housing keeps the package compact for enclosed machine spaces. The motor has length code C and frame size 025, and it is built without a shaft seal, which is better suited to clean installations where external sealing is not required.
